The format to use is specific to your company. When you search for a phone number through the search tool in CentrixOne, the system will perform the search ignoring characters that are not numbers.
So this means that if you search for the phone number “(514) 123-1234” in the search tool, you must enter “p:5141231234.” Thus, the system will display all the possibilities listed in your example, even if you have added an extension number.
(Note that the “p:” is used to tell the system to target your search in a phone field.)
